What Is Swollen Upper Arm and Pain?
Swelling and tenderness in the upper arm may indicate a health concern. This condition often involves fluid buildup, stiffness, or reduced mobility. It can arise from localized injuries or systemic issues affecting the body.
Pain in this area can be localized or radiate from other regions. For example, heart problems might cause referred pain in the upper arm. On the other hand, injuries like strains or fractures lead to direct discomfort.
The lymphatic system plays a key role in swelling. When drainage is impaired, protein-rich fluid accumulates, causing lymphedema. This is a common symptom in cases of chronic swelling.
Inflammation from injuries or infections can also trigger fluid retention. This response is the body’s way of protecting and healing damaged tissues. However, persistent swelling may signal underlying conditions like autoimmune disorders or heart disease.
| Type of Pain | Cause | Description |
|---|---|---|
| Localized | Injuries, strains | Direct discomfort in the upper arm |
| Referred | Heart issues | Pain radiating from other areas |
| Chronic | Lymphedema | Fluid buildup due to impaired drainage |
